Writing in the Mathematics Classroom -- Explanation and Evaluation

Pupils engage in an activity where one partner reads directions while the other follows those directions to complete a math task (such as bisecting an angle). As a reflection, they examine products to see what information the best...

Let Y represent Yes to using an excellent resource. Pupils first learn to define variables using a complete description in the 19th part in a series of 36. They write expressions involving addition and subtraction in real-world contexts...

Practice writing algebraic expressions from written phrases. The objective is to consider two seemingly similar phrases, write them as algebraic expressions, and then simplify using the order of operations. Learners are challenged to...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is taken to discuss...

To add or subtract ... how do you make the decision? The video instructor explains the process of writing a numerical expression from a verbal expression. While writing the expressions, he provides explanations for his decisions.

Products, quotients, sums, and differences are the operations to know. A thorough lesson presentation explains how to analyze a verbal expression to create a mathematical expression. Explanations of terminology and order help learners...

Evaluating expressions require two things- parentheses and PEMDAS. The video starts with an emphasis on using parentheses to plug in your variables. Once you have everything plugged in, PEMDAS will get your mathematicians to the correct...

Introduce exponents to your learners with this quick video about writing numerical expressions. It explains the foundation of exponents and demonstrates a few examples. Use with other four videos in the series for examples on evaluating...

The use of manipulatives creates a playful atmosphere in your classroom. Using precreated disks, pupils translate verbal expressions into mathematical equations, offering a great way to practice the new vocabulary in a nonthreatening...

How do algebra learners know the value of an algebraic expression that contains a variable? This video shows your number crunchers how to evaluate an algebraic expression by substituting a given number for the variable. In fact, it...
